What is Erosion?

• When waves lose energy and leave sediments / sand along a coast.
• The wearing away of land, removal of beach rocks/sand by water or wind.
• An area of land that smells different to other places.
• An area that has a lot of wind.
  

What is Deposition?

• When waves lose energy and leave sediments / sand along a coast.
• The wearing away of land, removal of beach rocks/sand by water or wind.
• An area of land that smells different to other places.
• An area that has a lot of wind.

What is the erosional process in which rocks are pushed by waves up against the headland, eroding the cliff face further?

• Hydraulic action.
• Abrasion.
• Attrition.
• Solution.

What is swash?

• Water that runs back into the ocean.
• Water that falls forward and moves up the shore.
• Tug of war between the drag of the wind and pull of gravity.
• Swirling of water in an area.

What are destructive waves?

• Waves that are tall and frequent, crashing into shoreline, digging out chunks of the shore.

• Long and low waves, beginning far out in the sea, with a smooth gentle landing.

• The circular movement caused by wind and gravity fighting.

• When people wave their hand to aggresively destroy things.
